    Temperature and frequency-dependent conductivity of polystyrene/polyaniline composite
    (University of Eloued, 2019-02-24) Bourib Fatima Zohra; Mezdour Douniazad; Tabellout Mohamed
    The electrical properties of polyaniline and polystyrene/polyaniline materials are investigated using the dielectric relaxation spectroscopy. The measurements showed that Polyaniline has a conductivity of 10-5 S/cm, while polystyrene/polyaniline exhibits nearly10-6 S/cm. The observed increase in conductivity with temperature is a property of semiconductor but the decreasing conductivity above 293.5K could be due to the presence of absorbed water and its removal may have caused structural changes in the hygroscopic PANI polymer chains
